Abstract
A hollow vertical housing contains vertical output shaft and gearing. A rotatable handle disposed on the outside of the housing, when rotated, by means of the gearing causes the shaft to rotate at such higher speed. Cutter blades in a hollow container which is sealable by removable lid can be rotated by the shaft to produce the desired blender action. Flywheel means causes the shaft to continue to rotate at essentially constant speed as new material is added for blending. In addition continued rotation of the shaft enables a quick release mechanism to disengage.
Description
This invention is directed toward a manually operable device wherein a handle rotatable by an operator is connected by suitable gearing to an output shaft in such manner that rotation of the handle causes the shaft to rotate at such higher speed. Cutter blades disposed in a hollow container can be rotated by the output shaft to produce a blender action. Other types of apparatus such as food mixers and grinders can be used in place of the cutter blades if desired. A flywheel can be used to enable the shaft to continue to rotate at essentially constant speed as new material is added for blending. In addition continued rotation of the shaft enables a quick release mechanism to disengage.
This invention can be used conveniently on camping trips, picnics and the like when no electric power is available and of course can also be used in emergency situations of power failure.
FIG. 1 is an exploded view of the housing.
FIG. 2 is a partially cut away exploded view of container and cap.
FIG. 3 is a cross sectional view of the invention.
FIG. 4 is a detail view of the handle disconnect mechanism.
Referring now to FIGS. 1-4, hollow housing 54 has top and side holes 56 and 58 with a large suction type cup 54 controlled by manually operable adjusting means 60 to secure the bottom of the housing by suction to a table top or the like, if desired, to prevent undesired movement or vibration during use of the invention. A detachable side mounted clamp 42 can be used to clamp the housing to an edge of the table.
First and second vertically spaced horizontal rods 30 and 62 extend longitudinally within the housing. One end of the upper rod 30 extends into removable sleeve 50 freely rotatable thereabout. Handle 26 is secured to the outside end of the sleeve. The inner end of the sleeve and adjacent center of gear 10 (also freely rotatable about rod 30) carry spring loaded quick disconnect cooperating coupling means 52. A spring is in the connecting grooves of the means applying pressure to outer and inner facings. Pushing handle 26 inwardly interconnectes the means 52 whereby manual rotation of the handle rotates gear 10. (Means 52 can be disconnected by pulling handle 26 outward.) Initially when the operator starts the cranking operation, he must push inward on the handle to engage the grooves. The moment the operator stops turning, he still has a slight hold on the handle. The forward motion of the shaft allows the grooves to disengage and the spring to push the handle out.
The gearing and shaft connections and dimensions are chosen to enable gear ratios of 9:1 between gears 10 and 16 and likewise between gear 18 and 12 whereby each rotation of handle 26 will cause shaft 24 to rotate eighty one times. Once the shaft 24 is up to desired speed, flywheel 20 will generate a force which will tend to keep the shaft rotating at constant speed even when additional material is to be added for blending. This force also adds momentum and reduces the normal labor involved in operation.
Hollow pitcher like container 36 with removable top cap or lid 40 has rotatable cutter blades 36 with vertical bottom shaft 64. Rotation of shaft 64 produces rotation of the blades 36. Shaft 64 snap fits into the bore 62 of shaft 24 to enable blades 36 to be rotated when shaft 24 rotates. One method of preventing slippage between shafts 24 and 64 is to construct bore 62 and shaft 64 with square cross sections.
Thus a manually operable blender is provided which can be used easily in locations where electric power is not available. Of course, many other types of devices operating by rotatable shafts can be substituted for the blade carrying container and can be driven by shaft 24 in the same manner as the blender.
The gear ratios can varied from those given above to increase or decrease the speed of rotation of the shaft for a given manual input.
While the invention has been described with detailed reference to the drawings, the protection sought is to be limited only by the terms of the claims which follow.
